travel to us liquid restrictions

Here's the 411 on the TSA's 3-1-1 liquids rule

We've all been there. Waiting in the Transportation Security Administration line only to hear agents call for a "bag check," often because a traveler had a liquid product in their carry-on that's over the allowed limit (or some sort of other prohibited item).

It's a process that can sure slow things down, particularly on the busiest travel days. As you pack for your trip and consider what to put in your carry-on or checked luggage, it's important to consider what the TSA's limits are for liquids and similar products.

Since September 2006, the TSA has gone by the 3-1-1 rule when it comes to those types of products, including items like toothpaste, shampoo, conditioner, mouthwash and lotion -- sunscreen included.

In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container ("3"), all containers must be placed inside one clear quart-size plastic bag ("1") and each passenger is only allowed one plastic bag ("1").

If you meet those requirements, you should get through security without issue. However, if your liquid items are larger than 3.4 ounces each, you'll have to leave them in your checked bag.

There are a few exceptions, though.

The TSA has kept in place a temporary pandemic exception to the rule, allowing up to 12 ounces of liquid hand sanitizer in carry-on baggage.

Part of this exception: The hand sanitizer will have to be screened separately since it's technically over the limit. You'll need to remove it from your bag before it goes through the scanner.

There are also exceptions for larger amounts of medically necessary liquids, gels and aerosols. You can bring those products in larger, "reasonable" quantities, the TSA's website says. However, you must declare those items to security officers at the checkpoint for inspection.

This could, obviously, take a little more time than if you're traveling without those items.

This exception doesn't include sunscreen, despite calls to relax sunscreen restrictions at TSA checkpoints. Like other liquid products, sunscreen bottles over 3.4 ounces must go in your checked luggage.

There are also many liquids you cannot bring with you .

You can bring creamy cheeses, liquid chocolate, liquid coffee, creamy dips and spreads, gravy, honey, hummus, ice cream, jam, jelly, juice, syrup, peanut butter, salad dressing, sauce, salsa, soda, soup and yogurt as long as they are in a container of less than 3.4 ounces according to the TSA .

Related: Should you get TSA PreCheck or Clear — or both?

And yes, you can bring your water bottle with you, even if it weighs more than 3.4 ounces — as long as it's empty. This can also be a great way to save money at the airport, since -- as the TSA points out -- many airports have filling stations for reusable water bottles.

When in doubt, consult the TSA's list of what you can carry through the airport and check with your airline.

Whether you’re a carry-on-only kind of person or not , knowing the Transportation Security Administration’s (TSA) liquid limits is essential for anyone who travels by plane in the United States. Yet understanding which of your toiletries, foods, and other items even count as “liquid”—let alone how best to pack them—can get confusing. Use this guide to understand the TSA’s rules and restrictions about liquids, common exceptions, and tips to help ensure your next airport security screening goes smoothly.

What is the TSA liquid limit?

The TSA’s liquid limit for carry-ons—known as the 3-1-1 rule—allows travelers to pack liquids, aerosols, gels, creams, and pastes under 3.4 ounces (100 milliliters) in their carry-on bags. Passengers are allowed up to one quart-sized bag per person , or roughly nine 3.4-ounce containers in a single quart-sized bag. Anything more will have to go in a checked bag or risk being tossed out.

If your liquids are stored in containers larger than 3.4 ounces, even if there’s only 3.4 ounces left inside the bottle, you can’t bring them through security.

Completely empty bottles, such as your reusable water bottle , are allowed through the TSA checkpoint since (spoiler alert!) they don’t contain any liquids at that moment.

Which toiletries TSA allows in your carry-on

The TSA allows all of the following common toiletries in your carry-on only in containers that are 3.4 ounces or less:

• Shampoos and conditioners
• Lotions and sunscreen
• Gel hair products

In other words: yes, you can bring toothpaste, deodorant, and sunscreen through TSA checkpoints but only if they are in travel-sized containers.

Powders and powder-like substances, including baby powder and some makeup items, aren’t restricted in your carry-on bag. But if you’re carrying more than 12 ounces (350 milliliters) of a powder, you’ll need to place it in a separate bin for X-ray screening, and it may be subject to additional screening—so it’s a good idea to budget an extra few minutes at the security checkpoint if you think this might happen.

Tips for packing your toiletries in your carry-on

To comply with TSA regulations, invest in small, reusable toiletry bottles, like these capsules by Cadence.

Especially if you don’t have TSA PreCheck , it’s helpful to pack all of your toiletries in a quart-sized (or smaller) clear plastic toiletry bag for screening. Although improved airport technology means that far fewer air passengers (both in PreCheck and non-PreCheck lines) will have to take their liquids out out of their carry-on, it’s still helpful to have all of your liquids in one bag just in case you get pulled aside for additional screening. For an upgrade from that large Ziplock, we recommend the standard-sized Clarity Jetset Case from Truffle ($88), which has a clear window panel and is comparable in size to a quart-sized bag.

Since toothpaste is considered a liquid, paste, or gel by the TSA, most of us toss those tiny one-ounce tubes in our carry-on bags. However, if you want to ditch the hard-to-recycle packaging, consider toothpaste tablets, an ecofriendly alternative that’s not subject to the 3-1-1 rule. We like Humankind’s fluoride toothpaste tablets ($12), which resemble small mints and turn to paste when you crush them between your teeth. Matador has also recently released a reusable toothpaste tube ($10), which you can fill (and refill) with your regular toothpaste.

For travel toiletries that are easy to rebottle (like shampoo or body wash), consider investing in reusable bottles or containers so you can always keep your preferred brand on hand. Some of our favorite TSA-approved toiletry bottles include:

Buy Now: GoToob three-pack of 3.4-ounce bottles, $30, rei.com

These easy-to-fill, leakproof silicone tubes are ideal for shampoos, conditioners, lotions, and body washes. GoToob’s line comes in a variety of sizes, ranging from 1.7 to 6 ounces, and are easy to clean between refills.

Matador FlatPack

Each three-ounce, TSA-approved bottle is made from a durable, waterproof, nylon-based fabric. Like GoToob, they’re leakproof and easy to fill, but thanks to their flexible, fabric-like design, they will shrink to their contents, taking up less space in your pack. >> Read the full review of the Matador FlatPack

The refillable travel containers by Cadence are small, leakproof “capsules” that click together with magnets. At 0.56 ounces, they’re best for makeup and toiletries you don’t need much of—like a weekend’s worth of shampoo or a week of that under eye cream you only need a dab of.

Foods are subject to liquid limits

The TSA’s 3-1-1 rule applies to food too, meaning you’ll need to make sure any foods that count as liquids, gels, or pastes (like yogurt, peanut butter, pâté, jams, or that tasty pimento cheese spread you tried to bring home from Charleston) are less than 3.4 ounces or packed in your checked bag. There are some exceptions, like frozen foods and juice for babies, and the TSA’s website is the best resource to check for specific items.

Exceptions to TSA’s liquids rule: Full-sized liquids that you can bring through security

The TSA has several important exemptions to its liquids rule. You’re allowed to bring full-sized bottles of the following:

Hand sanitizer: Due to the coronavirus pandemic, the TSA currently allows travelers to bring up to 12 ounces of hand sanitizer in their carry-on bags. These will be screened separately.

Medication: You’re allowed to bring medically necessary liquids, aerosols, and gels through security. This also includes the ice or gel packs you may need to keep your medications cool. You are not required to store these items in a plastic, resealable bag, but you should remove them from your luggage and let the TSA officer know what you’ve packed.

Baby formula and breast milk: Like medication, you can bring freezer packs to keep these items cool, and you should remove them from your luggage and notify an agent when you go through security. More baby-related exceptions? Gel or liquid-filled teethers and canned or jarred baby food.

Of course, the final decision on whether an item is allowed through the checkpoint rests with the TSA officer.

If you’re ever unsure about a specific item, the TSA’s website has a handy, searchable list of prohibited and allowed items worth checking before you travel. You can also now text the TSA with your questions.

TSA Liquid Rules Ultimate Guide (3-1-1 Explained) [2023]

Bringing your liquids through airport security is not always as straightforward as you might think.

There are several rules that apply when bringing your liquids through airport security checkpoints and, yes, many are obvious to those of us blessed with a shred of common sense.

But in some cases there are some less obvious restrictions that could apply to your liquids.

And when you start talking about things like baby essentials, medications, and liquids like alcohol, there are many lesser-known rules and exceptions that come into play.

Violating these rules can sometimes mean slowing down the flow of the screening checkpoint (something we all should want to avoid) but in other cases it could mean violating the law and you basically becoming an airport criminal.

And nobody wants that.

So it’s a good idea to get acquainted with how these rules work and in this article, I’ll give you a detailed breakdown of the 3-1-1 rule and also talk about the many different types of exceptions and additional rules that apply to different types of liquids such as medications and alcohol.

What is the TSA Liquids “3-1-1 Rule?”

The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 liquid ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag.

Where does the 3-1-1 come from?

It’s just an easy way to memorize the different requirements that make up the rule and I’ll hit on those below.

3.4 fluid ounces or (100 mL)

The “three” indicates that your liquids must be contained within a container no larger than 3.4 fluid ounces or (100 ml).

(TSA uses 3.4 ounces because it’s easier to remember but really  100 ml comes out to 3.3814 fluid ounces. )

One of the biggest things that people get confused about is that the 3.4 ounce requirement applies to the size of the container and not the liquid within the container.

So let’s say that you have a 6 ounce container with only 2 ounces of fluid inside.

You may think that because you have under 3.4 fluid ounces of liquid, you are good to go but because your container is larger than 3.4 ounces, you cannot bring that through TSA.

The other big thing to know is that this refers to fluid ounces which relates to volume and is very different from ounces used for weight.

Some products like honey could weigh 4 ounces but still fit inside of a 3.4 fluid ounce container. It helps to know how to convert ounces/grams to fluid ounces .

1 quart-sized resealable bag

The first “one” means that your liquids must fit within 1 quart-sized resealable bag. Typically, this will be a clear Ziploc bag which just makes things easy for everybody.

The key thing to note here is that the containers must fit “comfortably” inside this resealable bag.

What does “comfortably” mean?

It basically just means that the bag is not bursting at the seams. (Think about how a pair of jeans should fit when you’re being honest with yourself about your waist size.)

If you are not able to easily reseal your bag, then your contents may not be fitting comfortably inside.

In such a scenario, it’s possible that a TSA agent could ask you to throw something out in order to allow your bag to comply with the rules.

In my personal experience, I have not seen a lot of TSA agents enforce the “comfortable” requirement very strictly but if you have bottles poking out of your liquids bag, I could see that being an issue.

1 quart size bag per person

The last requirement is that you are allowed 1 quart size bag per person.

The easiest way to comply with this is to simply separate your liquids bag from your carry-on and have one liquids bag in your bin when going through security.

Otherwise, it could look like you are trying to bring through two bags of liquids.

The best packing tip I have for this is to keep your liquids bag at the top of your carry-on so that you can easily retrieve it.

There’s nothing worse than scrambling to find that liquids bag while trying to get ready to go through a screening checkpoint.

TSA Pre-Check liquids rule

TSA Pre-Check allows you to bypass the main security line and pass through a screening line that is usually much shorter and quicker. This also means avoiding the full body scanner in many cases. It basically makes you a VIP when it comes to airport security checkpoints.

If you have TSA Pre-Check , you can take advantage of several benefits including things like:

• Shoes can stay on
• Belt can stay on
• Light jackets can stay on
• Laptops allowed to stay in bag
• Liquids (3-1-1) can stay in bag

That last perk is the most relevant to the liquids rule as you will not have to remove your liquids bag and place them in one of the bins when going through security. You can simply leave them in your carry-on and pass through the metal detector without any issue.

I highly recommend that you look into getting Pre-Check in order to expedite your security screening. It will only cost $78 for five years and all you have to do is pass a background check. You can also get it if you are approved for Global Entry ( read how to get approved here ).

New hand sanitizer liquids rule

Due to the ongoing threat of coronavirus and the potential threat of spreading germs throughout airports and aircraft, TSA recently implemented a change with respect to hand sanitizer.

Passengers will now be allowed to bring one hand sanitizer bottle up to 12 ounces. These larger bottles will be screened separately so just be aware that it could add some extra time.

What exactly is a “liquid?”

In some cases, what constitutes a liquid will be very clear.

For example, it’s pretty much common sense that water inside of a water bottle is a liquid. The same applies for cologne, mouthwash, etc.

But liquids also can include less-obvious forms like aerosols, gels, creams, or pastes.

This means that several common items you would be bringing along for your trip could be considered a liquid like: toothpaste , lotion , sunscreen, shaving cream, shampoo , conditioner, and others.

You can find travel-sized products for most of these so it’s usually pretty easy to bring along items that comply with the TSA liquids rule.

Other items

You need to be mindful of other items that could be considered liquids like deodorant . For example, the following types of deodorants will be subject to the 3-1-1 rule:

• and Roll-On deodorants

Prohibited items

Just because you have something like an aerosol and it is in a container no larger than 3.4 ounces, that does not mean that you can bring it as a carry-on.

There are quite a few prohibited items like aerosol insecticide, bear spray, etc. that are not allowed as carry-ons. In fact, some of those items may not even be allowed on the plane at all. This is a good place to search if you are in doubt about whether or not you can bring a particular item.

Be aware that some items like hairspray may even have size restrictions when packed in your checked baggage.

Foods can also be liquids

One aspect of the TSA liquids rule that throws a lot of people off is that they forget many foods also qualify as liquids.

Here is a non-exhaustive list of food items that will fall under the liquids rule:

• Liquid chocolate
• Creamy dips and spreads
• Mashed fruits such as applesauce
• Jam and jelly
• Maple syrup
• Oils and vinegars
• Peanut butter
• Wet pet food
• Salad dressing
• Salsa and sauces

Basically anything that is usually poured, scooped, squeezed, slurped, or mashed will be considered a liquid for TSA purposes.

If your food is solid on the other hand , chances are you can bring it through.

TSA rules for liquid medications

The liquids rule provides exceptions for medical supplies and medications .

TSA allows larger amounts of medically necessary liquids, gels, and aerosols in “reasonable quantities” than your 3-1-1 allowance.

You do not have to have a prescription for these items but keep in mind that you need to comply with state laws regarding prescriptions and controlled substances.

This leaves two questions often to be asked and answered.

The first is what is considered “medically necessary?”

For example, is contact lens solution medically necessary?

It seems the answer to that is probably yes given the TSA states, they allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip” on the page regarding contact lenses.

So if in doubt check the website and then inquire with AskTSA if you still don’t know.

The second question is what is considered a “reasonable quantity?”

What is deemed as a reasonable quantity is a subjective determination.

According to the TSA, you should bring what’s necessary for the duration of your trip (e.g., seven days) plus a day or two just in case things get delayed or canceled.

If you stick to what you think will be necessary for the duration of your trip, I don’t think you will often run into trouble. But if you’re bringing a six month supply of medication on a four day getaway, that’s when you might start to run into trouble if questioned.

TSA states that you must declare them to TSA officers at the checkpoint for inspection.

You also want to remove these from your carry-on so that they can be screened separately from your belongings. (You do not have to put your liquid medication in a plastic Ziploc bag.)

Just be aware that if one of your liquid items declared as medically necessary sets off the alarm, it may require additional screening and may not be allowed.

Baby essentials

You are allowed to bring formula, breastmilk, and juice for infants or toddlers in “reasonable quantities” through airport security. According to the TSA, reasonable quantities for baby essentials typically means the duration of the flight.

When bringing these items through security, be sure to separate these from your carry-on bag so that they can be screened separately from the rest of your items.

If you are carrying liquids in excess of 3.4 ounces, you are advised to inform the TSA officer at the beginning of the screening process that you have excess liquids. You can do this when you are unloading your items into the bin.

In many cases, excess liquids will be screened by x-ray.

It’s also possible that an officer may ask you to open up the container and potentially even transfer a small quantity of the liquid for testing.

If you are worried about the effects of an x-ray machine on your liquids, The Food and Drug Administration states that there are no known adverse effects from eating food, drinking beverages and using medicine screened by X-ray.

If that is not good enough assurance for you, you can ask to avoid the x-ray machine.

Additional steps may be able to be taken to clear the liquid but the traveler will likely have to undergo additional screening procedures which could include a pat down and a thorough screening of all of your carry-on property.

You will also be allowed to bring along ice packs, freezer packs, frozen gel packs and other accessories required to cool formula, breast milk and juice.

If these are in a partially frozen state or perhaps appear like a slushy they will be subject to the same screening as described above.

Other permitted baby items include gel or liquid-filled teethers, canned, jarred and processed baby food.

Just always be aware that these items may have to undergo additional screening.

TSA liquid rules for alcohol

Bringing alcohol through TSA presents a number of different challenges.

First, your alcohol in most cases will have to comply with the liquids 3-1-1 rule. This means that you won’t be able to bring in regular bottles of liquor or beer.

It is possible to find small bottles that are under 3.4 ounces (mini-liquor bottles are often around 1.7 ounces, so this means that they are small enough to be brought on the plane as a liquid).

But contrary to what many people think, it’s also permitted to bring your own alcohol in one of your own containers.

The catch is that there are specific restrictions about what type of alcohol is allowed on board and that can be allowed as a carry-on. You really need to make sure that you are abiding by these rules because you could be violating federal law otherwise.

The first regulation to know is that alcohol beverages with an alcoholic percentage above 70% (140 proof) is never allowed on the plane . In fact, alcohol with such a high alcohol percentage is considered a hazardous material.

If the alcohol content is above 24% but not above 70% then the alcoholic beverage must be in its retail packaging. A lot of popular alcoholic beverages for within this range. Here are some  ranges  for the alcoholic content of some common beverages:

Alcohol Percentage Content

• Vodka | ABV: 40-95%
• Gin | ABV: 36-50%
• Rum | ABV: 36-50%
• Whiskey | ABV: 36-50%
• Tequila | ABV: 50-51%
• Liqueurs | ABV: 15%
• Fortified Wine | ABV: 16-24%
• Unfortified Wine | ABV: 14-16%
• Beer | ABV: 4-8%
• Malt Beverage | ABV: 15%

And finally, one of the most important things to remember is that you are not allowed to serve yourself your own alcohol when flying.

Instead, you must request a flight attendant to serve you the alcohol or else you will be violating FAA regulations. Some flight attendants will happily serve you your own beverage but others will not be so inclined.

If you purchased alcohol at duty free store, different rules apply in that scenario. Basically, you can bring your duty free alcohol through TSA security but you have to comply with three separate requirements:

• The duty free liquids were purchased internationally and you are traveling to the United States with a connecting flight.
• The liquids are packed in a transparent, secure, tamper-evident bag by the retailer and do not show signs of tampering when presented to TSA for screening.
• The original receipt for the liquids is present and the purchase was made within 48 hours.

Checked baggage liquid rules

Many times, you can simply place your liquids in your checked baggage and not have to worry about that pesky 3-1-1 rule.

This is usually the way to go on longer trips when you might be bringing large quantities of things like shampoo or shaving cream.

But as mentioned above, you still need to make sure that the type of liquid is allowed on a plane. Certain materials may be considered hazardous and you could be violating the law by bringing those on board.

If you are loading up your checked baggage with a bunch of liquids, make sure that you double bag if there is potential for the liquids to spill!

TSA Liquid Rules FAQ

The TSA 3-1-1 rule does not apply to checked baggage. However, there are some restrictions on what liquids can be transported in your checked baggage. There may also be limitations on the quantity of liquids when it comes to importing large quantities of things like alcohol. At some point, you might have to obtain a license for certain goods.

TSA definitely enforces the liquids rule and I would recommend not trying to circumvent the rule. It’s possible that an agent may be more lenient than another in certain circumstances but I would always assume that an agent will be enforcing strictly so that I don’t run into any unexpected issues.

TSA has the rules in order to detect potential explosives and other harmful materials that exist in liquid state.

The same liquid rules apply for both domestic flights and international flights. One difference that you might encounter is when you purchase duty free goods before an international flight. See the duty-free section above for more details. Also, when flying internationally it is recommended that you get to the airport extra early. It is possible that you could get hit with SSSS and be forced to undergo a heightened security screening, so always plan out extra time.

While you might view your makeup as special, there are no special rules for your makeup when it comes to TSA. They must abide by the same 3-1-1 rule explained above. Read more about makeup rules here.

No, you do not have to take out your liquids if you have TSA Pre-Check.

The same TSA liquids rule will apply to all airlines. So if you’re flying American or Delta, the rules will be the same as if you were flying Southwest or United. With that said, some airlines do have some differences in how they handle acceptable baggage so you should make sure to read up on the latest baggage policies for the airlines.

If you are traveling from an “international last-point-of-departure” to the U.S ., powder-based substances in carry-on baggage greater than 350mL or 12 oz. may require additional screening. If your substance is over 12 ounces and cannot be cleared it will not be allowed onto the aircraft cabin. TSA recommends that you transport powders in your checked baggage.

TSA has several rules you need to follow when it comes to drinking liquids through airport security. The most well-known is the 3-1-1 rule but there are other considerations you need to think about like foods that might trigger the rule and exceptions for medical and baby essentials. In the end, try to be as reasonable as possible with what you are bringing through and you will run into few problems.

Everything You Need to Know About TSA Liquid Rules

Here's what to know before you fly with shampoo, medication, or any other liquids you may need during your travels.

Dealing with airport security can be one of the more daunting aspects of air travel , from the detailed rules about what you can and can't bring on board to the long lines that often form at checkpoints.

One rule that frequently trips up travelers is the Transportation Security Administration's (TSA) 3-1-1 regarding liquids in carry-on bags . We're here to walk you through the finer details of the rule and provide helpful tips for packing liquids when you're flying.

What is the TSA's 3-1-1 rule?

In 2006, British security officials thwarted a plot to bomb an aircraft with liquid explosives carried on board. Since then, security agencies around the world have limited the amount of liquid passengers can bring through airport security.

For the TSA, which regulates travel in the United States, all liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less. All liquids must fit into a single, clear quart-size bag — passengers can only pack one of these bags in their carry-on.

The 3-1-1 designation is a simple way to remember these numbers: individual liquid containers must be 3.4 ounces or smaller, they must fit into one clear, quart-size bag, and there is only one bag allowed per passenger.

Liquids that do not comply with the 3-1-1 rule must be packed in checked bags, or thrown out at airport security. Some liquids, such as gasoline or other flammable liquids, are prohibited entirely, both in checked and carry-on bags. You can find a full list of permitted and prohibited items on the TSA's website .

If you're unsure if a specific item adheres to the 3-1-1 rule, you can always contact the TSA before your trip. "Tweet your questions and comments to @AskTSA or via Facebook Messenger , weekdays from 8 a.m. to 6 p.m. ET," TSA spokesperson Jessica Mayle tells Travel + Leisure . "You can also call the TSA Contact Center at 866-289-9673."

Are there any exceptions to the 3-1-1 rule?

The TSA does exempt some items from the 3-1-1 rule: medically necessary liquids, formula, and breast milk. You can bring more than 3.4 ounces of these liquids on board, but you may have to undergo additional security screening.

"Inform the TSA officer at the beginning of the screening process that you're carrying them," says Mayle. "These liquids are typically screened by X-ray, but TSA officers may also test them separately for explosives or concealed prohibited items. Officers may ask you to open the container and/or have you transfer a small quantity of the liquid to a separate empty container, or dispose of a small quantity, if feasible."

If you don't want your exempt liquids to be screened by X-ray, inform your TSA officer, and they will use alternative security measures to clear the items.

And that's not all. "There's an exception for hand sanitizer, which has a temporary 12-ounce limit," says Mayle. But as COVID-19 travel restrictions and protocols continue to lift, the temporary special case for hand sanitizer could change, too.

Another exception is liquids purchased after security in an airport. In domestic U.S. airports , you can bring nonalcoholic drinks and other liquid items purchased airside onto your flight. (This is not always the case in international airports.) Duty-free liquids, however, will be sealed in a tamper-safe bag before boarding — sometimes they're permitted in the cabin, and other times they may be stowed elsewhere on the plane.

Packing Tips for Liquids in Carry-on Bags

• While many products are sold in 3.4-ounce containers suitable for travel, not all of them are. Consider rebottling your liquids into travel-size, leak-proof cases.
• "Another way to save space in your quart-sized bag is to pack solid versions of products, which you can put in your luggage or carry-on bag without needing to place it in the quart-size bag," travel advisor Ateet Ahuja of Complete Getaways tells T+ L. "For example, you can bring a stick or solid version of some perfumes and shampoo bars instead of liquid shampoo."
• Buy your liquids, like shampoo or mouthwash, at your final destination. "While you'll spend a little extra, the cost far outweighs the potential of it spilling or leaking in your bag," says Ahuja.
• On that note, prepare for spills — Ahuja advises wrapping a small hand towel around your quart-size bag.
• Pack your nonliquid toiletries separately to save space in your quart-sized bag.
• Pack your liquids bag in an easy-to-access space, like an external compartment or the top of your carry-on bag. According to Ahuja, "This will save you time in the TSA line."

Calling All Travelers: These Are the Official TSA Liquid Rules

You don't want security to throw away your new, full-size bottle of shampoo do you?

Every item on this page was chosen by a Town & Country editor. We may earn commission on some of the items you choose to buy.

We've all fallen victim to TSA while traveling; here's a refresher so you don't make the same mistakes again.

TSA Liquid Rules:

According to the TSA website , these rules apply for liquids, aerosols, gels, creams, and pastes.

All liquids must be in a 3.4oz or smaller container. Your serums, creams, cleansers, and masks are too expensive to lose, so check their sizes and if they're too big, leave them at home or transfer them to a smaller container.

They have to be able to fit in a quart-size bag. Before you throw 10 containers of liquids into your carry-on, make sure that everything can fit in a quart-size bag. Think about what you really need for your trip, a la Marie Kondo , and remember you can always buy things once you arrive at your destination.

Powders must be in 12oz containers or smaller. TSA placed new restrictions on powders in 2018. Ensure that your makeup, protein powder, and baby powder are in containers within that range, or put them into a checked bag.

Anything else has to go into a checked bag. If you can't part with your full-size products, they have to go into a checked bag to avoid getting tossed into the TSA product graveyard. If you're looking to save money, share one checked bag with your whole group.

Only empty water bottles will pass the TSA checkpoint. If you bring a refillable water bottle, make sure it's empty before you approach security. You can fill it up after you go through the checkpoint or buy water in the terminal.

There are exemptions. If you use a medication that comes in liquid, aerosol, gel, cream, or paste form and the container is larger than 3.4oz, it's exempt from the above rules. Similarly, if you're carrying baby formula, breast milk, or other liquid foods for your child, these are also exempt.

Airline-specific carry-on luggage rules

Tsa liquid limits, how many ounces are allowed on a plane, additional tsa carry-on rules, final thoughts on tsa rules for carry-ons.

Whether you’re purposefully packing light or supplementing your checked luggage, it’s important to keep Transportation Security Administration (TSA) carry-on luggage size in mind when packing a bag and heading to the airport.

After all, not all airlines allow full-size carry-ons for free, and most have slightly different rules on carry-on bag size. Don’t get caught unaware at the gate; hefty baggage fees and inconvenience may await.

Here’s what you need to know about airline and TSA carry-on size allowances.

Airline carry-on dimensions differ depending on the carrier. When purchasing your flight, you’ll be able to see your carry-on and personal item limits.

A personal item is typically a small backpack, purse, briefcase, diaper bag, camera bag or any item of a similar size that can fit underneath the seat in front of you. A carry-on bag could be anything from a large backpack to a small rolling suitcase. But it’s less shape than size that matters, so here are carry-on luggage size restrictions for each of the major domestic airlines:

Alaska Airlines

On an Alaska Airlines flight, you can bring a carry-on and a personal item for free.

Carry-on bags are limited to 22 inches long, 14 inches wide and 9 inches high including wheels and handles. All three measurements shouldn’t add up to more than 45 inches.

For personal items, Alaska offers examples of a purse, laptop or briefcase.

Alaska doesn't list weight limits, but it says that passengers should be able to lift items that go in an overhead bin.

» Learn more: Guide to Alaska Airlines baggage and other fees

American Airlines

For an American Airlines flight, passengers get one personal item and one carry-on, no matter what type of fare is bought (elite members included).

Carry-on bags shouldn’t be larger than 22 inches long, 14 inches wide and 9 inches high including handles and wheels.

Dimensions of personal items should not exceed 18 inches long, 14 inches wide and 8 inches high.

There are no weight restrictions for carry-on luggage.

» Learn more: American Airlines bag fees: How they work, how to avoid them

Delta Air Lines

Delta flyers are allowed one carry-on bag and one personal item.

Including wheels and handles, measurements may not exceed 22 inches long, 14 inches width and 9 inches high. The total length plus width plus height of baggage must not exceed 45 linear inches.

For personal items, Delta says size examples are purses, small backpacks and laptops.

Three places have weight limits: Singapore (7 kg, about 15.4 pounds), Beijing (10 kg, about 22 pounds) and Shanghai (10 kg, about 22 pounds).

Frontier charges for both checked luggage and carry-on bags, and the price depends on the route you fly. It also varies depending on if you buy the bags before via the web or mobile app, at the ticket desk, or the boarding gate.

Carry-on bags must weigh less than 35 pounds and must not exceed 10 inches deep, 16 inches wide and 24 inches high. Bags must fit in the overhead bins.

Checked bags must be no longer than 62 linear inches (length + width + depth) and must weigh under 40 pounds. Bags weighing more than 40 pounds will incur additional charges per bag per direction. Bags weighing 41-50 pounds will cost you $50 more and bags weighing 51-100 pounds will cost $100 more.

Personal items cannot exceed 8 inches deep, 18 inches wide and 14 inches high.

» Learn more: Frontier baggage fees: How they work

Not all JetBlue passengers are allowed the same carry-on items. Passengers who bought Basic Blue fares get one personal item (except Mosaic customers who always get a carry-on). Blue, Extra Blue, Blue Plus and Mint fares allow one carry-on and one personal item.

Including wheels and handles, length, width and height measurements may not exceed 22 inches long, 14 inches wide and 9 inches high.

Personal items can be no more than 17 inches long, 13 inches wide and 9 inches high or smaller to fit under the seat in front of you.

There are no weight limits for carry-on luggage on JetBlue.

Southwest Airlines

Southwest is known for having a generous free checked luggage allowance, but carry-on restrictions are similar to most other airlines — one personal item and one carry-on per traveler.

Carry-on measurements should not exceed 24 inches long, 16 inches wide and 10 inches high.

Personal items are limited to 18.5 inches long, 8.5 inches wide and 13.5 inches high.

Southwest doesn't list weight limits for carry-on items.

» Learn more: The guide to Southwest baggage and other fees

United Airlines

Most travelers flying with United can bring one carry-on and one personal item, but if you’re traveling on a basic economy fare, you’re allowed one personal item only (unless you’re a MileagePlus Premier Member, are traveling internationally or have a MileagePlus credit card, like the United℠ Business Card ).

Including handles and wheels, the maximum dimensions for a carry-on are 22 inches long, 14 inches wide and 9 inches high.

Personal items are limited to 17 inches long, 10 inches wide and 9 inches high.

United doesn't publish weight limits for carry-ons.

» Learn more: What you need to know about United Airlines baggage and other fees

Depending on the airline you fly with as well as how long you’re traveling for, you might wonder whether you’re better off traveling with a checked bag rather than a carry-on . This can be especially relevant if you’ve got some liquids with you that exceed the TSA carry-on liquid limits.

Before you even make it to your departure gate, you have to clear a TSA checkpoint. This means you must adhere to the TSA liquid limit in order to make it through security.

Containers that are 3.4 ounces or less are allowed, but there are other rules to keep in mind as well.

Carry-on liquid limit

The TSA liquid rule — also known as the 3-1-1 rule (3 ounces, 1 bag per 1 person) — is straightforward: "You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item." Any liquids in larger containers will have to go into checked baggage (and are subject to overweight fees).

A basic clear, zip-top container qualifies as an eligible quart-size bag for passing through security.

The easiest way to manage the amount of fluids in your carry-on is to start with containers that are no larger than 3.4 ounces or 100 milliliters and your quart-sized bag.

The maximum carry-on liquid size and amount will depend on how much you can fit into your single quart-sized bag.

3-1-1 liquids rule exemptions

The 3-1-1 liquid rule has several exceptions if you're traveling with certain liquid medicines or baby food.

TSA allows larger amounts of certain medically necessary liquids, gels and aerosols in "reasonable quantities" for your trip. The amount allowed is not stated.

The only catch? You must declare the medication to TSA officers at the checkpoint for inspection, alongside any accessories associated with your medicine, such as freezer packs or syringes.

Labeling your medical items can help facilitate the screening process.

Formula and breast milk are considered medically necessary liquids, and thus exempt from the carry-on liquid limit. Water and juice for babies is also allowed in quantities greater than 3.4 ounces or 100 milliliters.

These child and infant nourishment items are allowed in carry-on baggage and do not need to fit within a quart-sized bag. You may also bring teethers that are gel- or liquid-filled and canned/jarred/processed baby food in your carry-on baggage.

Duty-free liquids

The final exemption to TSA liquid limits apply to duty-free liquids purchased during inbound international flights. It's important that these bags are secure and temper evident and stored in a transparent bag.

Be sure to keep the item's original receipt handy in case a TSA officer asks to see it.

» Learn more: Can you bring food through TSA?

The only flammables allowed in a carry-on are cigars, cigarettes, disposable and Zippo lighters, and dry batteries (like AAs or AAAs).

Camping and sports equipment

You can carry-on an air mattress with a built-in pump (by following special instructions), antlers, basketballs, footballs, baseballs, soccer balls, bike chains and bike pumps. Bicycle allowances vary by airline, but baseball bats, bear spray and bear bangers are never allowed — nor is aerosol insecticide.

Other items

There are some banned items, including knives, firearms and box cutters. A full list of which can be found on TSA’s website .

No matter which airline you fly with, first make sure you know what size carry-on you’re allowed to bring onboard and are familiar with (and prepared for) TSA’s carry-on restrictions, too. Then, you can expect a smoother and less stressful airport and airliner experience.

Guide to TSA Carry-On Liquid Restrictions

Guide to T SA Carry-On Liquid Restrictions is key to smooth air travel. So, let’s simplify these confusing rules, uncover what to do and avoid, and share some handy tips to help you sail through airport security with liquids.

Essentials of Liquids Rule

To start, let’s get a grip on the core basics of TSA’s liquids rule:

• 3-1-1 Rule: This primary rule permits travelers to carry liquids in containers up to 3.4 ounces (100 milliliters), tucked in a quart-sized, transparent, ziplock plastic bag. Each traveler gets one bag.
• Container Size : Beware of your container size. Anything beyond 3.4 ounces should be in your checked baggage, following the liquids rule.
• Medicines and Baby Stuff : Exceptions are given for essential liquids like medicines and baby formula. Keep these handy for review.

TSA Carry-On Liquid Restrictions

• Liquids: Pack toiletries like shampoo, conditioner, and lotion but stick to 3.4 ounces or less.
• Gels and Aerosols: Just like liquids, limit hair gel, toothpaste, and gel deodorants to follow the 3-1-1 rule.
• Drinks: The 3.4-ounce rule applies to beverages too. You might want to buy drinks after security.

Exceptions to the Rule

• Medications: The 3-1-1 rule does not apply to prescription and over-the-counter drugs. But remember, clearly label them for inspection.
• Baby essentials: Baby formula, breast milk, and baby food in reasonable amounts are okay. Remember, with these items, expect more screening.
• Duty-Free Buys: Liquids from the duty-free zone are permitted post-security, just show your receipt. Mind restrictions for connecting flights.

Smarter Ways to Pack

Want to ace the liquids rule? Here’s how to pack:

• Get Travel-Size Bottles: Buy smaller toiletries or place your loved items into mini, TSA-okayed bottles to fit the 3.4-ounce limit.
• Pick the Quart-Sized Bag: Have your clear, quart-sized bag within reach in your carry-on for a faster security check.
• Merge Items: Group together several small things in a single bag. This will save room and follow the liquids rule while keeping necessary items.

Guide to Security Checks

Kickstart your trip smoothly by mastering the art of liquid rules in security checks:

• Quart-Sized Bag Action: Your liquids should be in a quart-sized bag, placed separately in a bin during X-ray checks.
• Speak Up About Medication: If you have medications, alert the security crew. They might need delicate handling.
• Stay in the Loop: TSA guidelines can change. Stay updated to match their latest rules.

Blunders to Evade

Even frequent flyers can slip. Here’s what to watch out for:

• Missing Quart-Sized Bag: Remember to prepare your quart-sized bag. It could save time.
• Overlooking Duty-Free Caps: Bought duty-free liquids? Know the limit, especially for connecting flights.
• Misjudging the Liquid Types: Gels, aerosols, or liquids? Each has unique rules. Brushing up the facts could save you from shocks at the security gate.

Ending Notes

Mastering TSA Carry-On Liquid Restrictions is like learning an art – it’s all about preparation and knowledge. Get to know the rules. Learn what you can and can’t pack. Discover smart ways to pack.

Know what you can and can't include in your carry-on bag so you'll be best prepared for your next airport experience.

As all air travelers know, it can be incredibly frustrating to discover you've packed something that isn't allowed through airport security. Whether traveling for pleasure or business, you can make your flight smoother by understanding the restrictions affecting your carry-on luggage. Use this guide to take the hassle out of your next trip.

The 3-1-1 Rule or Liquids Rule

Carry-on allowances and restrictions are determined by the Transportation Security Administration. These rules apply to items in carry-on bags (carry-on-sized suitcases, backpacks, purses, laptop bag and mores) that you plan to take through security. The TSA's 3-1-1 rule outlines the travel limitations for liquids, aerosols, gels, creams and pastes. Here's a breakdown:

• 3: All travel-sized containers must hold no more than 3.4 ounces (100 milliliters) of liquid.
• 1: All containers holding liquids, aerosols, gels, creams and pastes must be placed within one sealed quart-sized bag.
• 1: Only one quart-sized bag is allowed per passenger, even if you have multiple carry-on bags for your flight.

Keep in mind that purchasing additional carry-on luggage will not allow you more of these restricted items. Additionally, containers that hold more than 3.4 ounces will not be allowed, even if they are not completely full.

The following list covers many of the items you're allowed to pack in your carry-on . Read on for more information on each type of item and what limits apply.

Sports and exercise equipment

Dietary supplements, blankets and pillows, medical items and equipment, razors and other hair removal tools, food and snacks, personal electronic devices and accessories, smoking paraphernalia, nature-related items, solid candles.

The top travel priority for any new parent is how to care for your baby while on a flight. While the 3-1-1 rule applies to most carry-on items, you'll be happy to know that items related to the care and feeding of your baby are less restricted. Baby formula, breast milk, toddler drinks, and food for babies and toddlers are considered medically necessary liquids by the TSA, so quantities larger than 3.4 ounces may be packed separate from the quart-sized bag in your carry-on baggage.

Accessories needed to transport these items, such as ice or freezer packs, are also allowed without restriction. These items can be transported even if you are traveling without the liquids or your child, but you must inform a TSA officer at the beginning of the screening process. To make your security experience smoother, TSA also recommends you transport any liquids in clear, translucent bottles rather than plastic bags or pouches. In addition, the following items can be packed in your hand luggage: a baby carrier, a child car seat, baby powder, baby wipes and a breast pump.

Whether you are a serious athlete or a casual player, most sports and exercise-related equipment is allowed in your carry-ons. The following sports balls can be included: basketballs, baseballs, footballs, soccer balls, golf balls, bocce balls and bowling balls. Sports cleats and helmets are also permitted. Golf enthusiasts can pack divot tools and tees, but there are restrictions for other golf equipment. If you're headed to a cold climate for some outdoor fun, you can pack your snowboards, snowshoes and ice skates. Crampons are also generally permitted in carry-on bags, but TSA officers can remove them at their discretion.

Your helmet, bicycle chain and bicycle pump can be packed, but bicycles, skateboards, hoverboards and segways may face restrictions based on your airline's carry-on policy. Additional sports and exercise equipment allowed in carry-on luggage includes rollerblades, longboards, boxing gloves, fishing poles, small fishing lures (with sharp objects properly sheathed), pickleball paddles, tennis rackets, foam yoga blocks and yoga mats. Sports equipment that can be used as a bludgeon, such as clubs or bats, is not allowed in the cabin.

Dietary supplements, protein powder and energy powders (like pre-workout and creatine) are all allowed in powder or pill form. If you are packing powder-like substances greater than 12 ounces (350 milliliters), be sure to place the containers in a separate bin for X-ray screening. They may require additional screening or need to be opened for testing.

These are not restricted by the TSA. If you don't yet have a travel blanket, U.S. News recommends the BlueHills Premium Soft Travel Blanket Pillow for airplanes. It doubles as a blanket or pillow for the plane. If you have a favorite pillow that you can't imagine sleeping without, have no fear: Pillows can be packed in your carry-on luggage without restriction. Or, consider one of U.S. News' top travel pillows .

Dealing with medical needs can be stressful enough without adding travel. If you're concerned about accommodating your needs, alert your airline at check-in to ensure you have a positive experience. Medications in pill form, including vitamins, are typically allowed without major restrictions, though destinations sometimes have their own regulations. Any liquid, gel or aerosol medications that are medically necessary (including insulin, EpiPens and inhalers) can be transported in excess of the 3-1-1 rule, but you must declare them to TSA officers at the checkpoint for inspection.

Pill organizers are a great option for traveling with basic medication, but prescriptions are best kept in their original packaging or clearly labeled. If your mobility is limited, inform the TSA officer at the checkpoint so accommodations can be made to screen you and your belongings safely and quickly. For more information regarding disability and medical conditions, check out the TSA's website or contact your airline.

Many makeup products are limited by the TSA's 3-1-1 rule for carry-on luggage. If you are traveling with any of the following, you will need to adhere to the 3.4-ounce restriction: concealer, liquid eyeliner, foundation, mascara, other liquid makeup and makeup remover. Solid and powder makeup are not restricted but will need to be placed in a separate bin for screening if they exceed 12 ounces (350 milliliters). Lipsticks, lip balms, makeup wipes and airbrush makeup machines can be packed in carry-ons without restriction.

The following cosmetics are also restricted by the TSA's 3-1-1 rule: hair gel, hairspray, aerosol hair texturizer, nail polish and nail polish remover. Nail clippers and metal nail files are unrestricted but should be sheathed to avoid injury. Hair styling tools like curling irons and straighteners should have their heating element safely covered if they're cordless.

Since many toiletries are subject to the TSA's 3-1-1 restriction, consider packing your carry-on items in a TSA-approved toiletry bag like one from PACKISM or check out U.S. News' picks for the best toiletry bags . Items subject to the 3-1-1 rule include liquid and aerosol deodorant, cologne, perfume, shampoo, conditioner, dry shampoo, lotion, sunscreen and toothpaste. Outside of your clear quart-sized bag, you can pack your solid deodorant, toothbrush (manual and electronic), tweezers and mirrors. For recommendations on eco-friendly travel-sized products, check out this piece on sustainable travel .

Disposable and electric razors are allowed without restriction, but sharp edges should be securely sheathed to avoid injury. Safety razors are allowed, but the blades must be removed and packed securely in your checked bag. Laser hair removal devices and hair clippers are not restricted, but shaving cream must adhere to the 3-1-1 rule.

All drinks are subject to the TSA's 3-1-1 rule, including bottled water, coffee and tea (in liquid form), juices, smoothies, soda, and alcoholic beverages up to 70%. TSA requests that you do not consume your personal alcohol in-flight. An airport's duty-free section is a great alternative to trying to pack alcohol.

If you prefer to travel with your own cup or container for beverages (such as a coffee thermos or water bottle), you will need to ensure it is empty before passing through security. You can fill empty beverage containers on the other side. Ice must be frozen solid when passing through security or it will be subject to the 3-1-1 rule.

Solid foods are allowed through security but may be restricted by your arrival destination, so be sure to check travel regulations for your destination. Some foods can cause obstructions during the X-ray process, so the TSA recommends you remove food items from your bag before screening. Allowed foods include bread, cereal, cheese (solid), cooked meat, cooked seafood, cooked vegetables (no liquid), fresh eggs, nuts, pies and cakes, pizza, salt, sandwiches, spices (dry), coffee (beans or ground), and tea (dry tea bags or loose tea leaves).

The following food items are allowed but restricted by the 3-1-1 rule: canned foods, cheese (creamy), chocolate (liquid), cream, creamy dips and spreads, gravy, honey, hummus, ice cream, jam and jelly, maple syrup, oils and vinegars, peanut butter, salad dressing, salsa and sauces, soups, and yogurt. Small snack foods can also be taken through security. This includes candy, chocolate (solid), cookies, crackers, dried fruits, gum, popped popcorn, nuts and snack bars. Fresh fruits and vegetables are permitted as long as your destination doesn't have any restrictions on the item.

Personal devices should be packed in a convenient location in your carry-on luggage because electronics must be removed from your bag and placed in a separate bin for screening. This includes cell phones, desktop computers, digital cameras, laptops and tablets. Consider purchasing a travel backpack with a separate pocket for electronics, like the Solgaard Lifepack Endeavour (with closet) , to make security a breeze.

Cigarettes, cigars, hookahs, tobacco and tobacco pipes are permitted without restriction, but you are strictly prohibited from using those items aboard most aircrafts. If you do pack these items, make sure any disposable or Zippo lighters are emptied of fuel and that any arc lighters, plasma lighters, electronic lighters, lithium-battery-powered lighters, e-lighters, electronic cigarettes and vaping devices are stored in a way that prevents accidental activation on the plane. This can include removing the batteries and either placing the item in a protective case or using a protective cover, safety latch or locking device. Any e-liquids must adhere to the 3-1-1 rule.

Batteries for commonly owned devices are allowed in carry-on bags. This includes dry batteries (AA, AAA, C, and D), lithium batteries, fuel cells and nonspillable wet batteries. Large batteries, such as those used for vehicles or wheelchairs, are typically restricted. If you must travel with a battery of this size, you should speak with a TSA agent and your airline prior to going through security. Additional information on battery restrictions can be found in the Federal Aviation Administration regulations .

While TSA doesn't restrict natural items like rocks or shells at security, it is important to check the restrictions for your arrival destination as many have restrictions to avoid the possibility of introducing an invasive species to a new environment. Assuming no destination restrictions, flowers can be brought through security if they are not in water. Live corals, live lobsters and live fish can be transported in water if they are in a clear container and have been inspected by a TSA officer.

Typically, any tools that are 7 inches or less in length are allowed in carry-on bags. Tools exceeding this length are restricted. Keep in mind that sharp objects must be properly sheathed to avoid potential injury. Multi-tools that do not have knives but do contain scissors shorter than 4 inches are allowed, but multi-tools with blades are prohibited.

You can bring one book of safety matches on board, but they must not be strike anywhere. Parachutes can also be brought as carry-on luggage but must be packed separately from other luggage. Flashlights are not restricted but be sure to check that the batteries meet TSA regulations before you pack.

Solid candles are unrestricted, but make sure to check the section below on what isn't allowed in carry-on bags to see what restrictions there are for other candle types.

These are allowed through TSA checks without restrictions, but you should check with your airline as each may have its own size and weight restrictions. A safe bet is to purchase an umbrella like the Weatherman Travel Umbrella which weighs less than a pound and measures just under 12 long when closed. It also comes with a handy sleeve to keep the rest of your luggage dry when stored.

Additional items

If there's an item you want to bring that you don't see covered in this article, do not fret. You can check with your airline or the AskTSA team for more information.

What Isn't Allowed in a Carry-on Bag?

Here is an overview of items that are not allowed in the cabin when you fly. Check the TSA page What Can I Bring? for a full list.

• Alcoholic beverages over 140 proof, or 70%, are not allowed.
• Weapons: You cannot bring knives (pocket, swiss army, utility, kirpans, razor-type blades), guns (BB, cap, pellet, compressed air), ammunition and gun powder, axes and hatchets, bows and arrows, firearms and rifles, martial arts weapons, and realistic replicas of weapons in your carry-on.
• Weapons (self-defense): These include kubatons, pepper and self-defense sprays, brass knuckles, blackjacks, night sticks, stun guns and shocking devices, and tactical pens.
• Explosives: Items creating or replicating an explosion are banned. This includes bang snaps, dynamite, English Christmas crackers, firecracker, fireworks, flare guns, flares, hand grenades, party poppers, sparklers and vehicle airbags.
• Certain sports and exercise equipment: Items that can be used as a bludgeon are not allowed in the cabin. TSA restrictions apply to clubs, bats, hockey and walking sticks, canoe and kayak paddles, bowling pins, darts, hiking and ski poles, ice axes and ice picks, shoe and snow spikes, snow cleats, starter pistols, and more.
• Certain medical items and equipment: Battery-powered wheelchairs and mobility devices, gel heating pads, and a mercury medical-clinical thermometer cannot be carried on.
• Tools: Restriction prohibit box cutters, crowbars, drills and drill bits, hammers, nail guns, saws and screwdrivers longer than 7 inches.
• Flammable gases and liquids: Be sure not to pack engines and engine-powered equipment, fire extinguishers and other compressed gas cylinders, fuels, spillable batteries, strike anywhere matches, flammable paints (liquid, gel, spray, aerosol), turpentine and paint thinner, and more.
• Safety razor with blades
• Gel-type candles

The rules and restrictions outlined in this article aren't the only things to consider when packing your carry-on. In addition to the 3-1-1 rule, travelers should be aware that some airlines have different regulations on the types of items, liquids, aerosols, gels, creams and pastes that are allowed onboard. This is particularly important when traveling internationally as restrictions differ by country. For example, New Zealand is a particularly restrictive country when it comes to traveling with foods, plants, seeds and grains due to its delicate ecosystem.

Confirm your destination restrictions before packing to avoid difficulties getting through customs when you arrive. TSA agents are also given the authority to make the final call on whether an item is allowed through security, so it's best to pack things you're uncertain about in your checked luggage rather than your carry-on.

Understanding The Liquid Restrictions When Traveling To The Us

• Last updated Aug 02, 2023
• Difficulty Intemediate

• Category United States

Are you a frequent traveler to the United States? If so, you're likely familiar with the strict liquid restrictions that have been put in place for air travel. This significant change has not only affected the way we pack and prepare for our trips, but it has also sparked debate and raised questions about the necessity and effectiveness of these restrictions. Join me as we delve into the world of US liquid restrictions and explore the reasons behind these rules, their impact on travelers, and the ongoing discussions surrounding this topic.

What You'll Learn

What are the current liquid restrictions for traveling to the us, how much liquid can be carried in carry-on luggage when flying to the us, are there any exceptions to the liquid restrictions when traveling to the us, can liquid items be packed in checked luggage when traveling to the us, are there any specific guidelines for carrying medications or medical liquids when traveling to the us.

Liquid restrictions for traveling to the US have been put in place by the Transportation Security Administration (TSA) to enhance security measures and prevent potential threats. These restrictions apply to both domestic and international flights departing from or arriving in the United States.

The current liquid restrictions are as follows:

• Containers Size: All liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less. This includes items such as toiletries, beverages, and any other liquids you may be carrying.
• Carry-On Limitations: All containers must be placed in a clear, quart-sized plastic bag. Each passenger is allowed only one bag. This bag should be easily accessible and presented separately to the security officer for screening.
• Bag Inspection: All passengers are required to remove the quart-sized plastic bag containing the liquid items from their carry-on baggage and place it in a separate bin for screening when going through security checkpoints.
• Medications and Baby Formula: Prescription and over-the-counter medications, as well as baby formula or breast milk, are allowed in quantities greater than 3.4 ounces (100 milliliters), but they must be declared to the security officer for inspection.
• Duty-Free Items: Passengers are allowed to carry duty-free liquids purchased at the airport or on board the aircraft. These items must be packed in a secure, tamper-evident bag and must be accompanied by proof of purchase.

It is important to note that these restrictions apply to liquids, gels, and aerosols only. Other items such as solids, powders, and non-liquid food items are not subject to these limitations.

It is advisable to check the specific guidelines of the airline you are traveling with, as they may have additional restrictions or requirements. Additionally, it is recommended to arrive at the airport with ample time to allow for the additional security screening procedures.

Understanding and following these liquid restrictions will help ensure a smooth and hassle-free travel experience when flying to the US.

New Travel Restrictions Implemented: Latest Updates on International Travel Regulations

When traveling to the United States, it is important to understand the restrictions and regulations regarding what you can bring in your carry-on luggage, especially when it comes to liquids. The Transportation Security Administration (TSA) has implemented specific rules to ensure the safety of all passengers on flights. In this article, we will explore how much liquid you can carry in your carry-on luggage when flying to the US.

The TSA follows the 3-1-1 rule for liquids in carry-on luggage. This means that each passenger is allowed to bring a quart-sized bag of liquids, gels, creams, pastes, and aerosols in containers that are 3.4 ounces (100 milliliters) or less per item. The quart-sized bag should be transparent and sealed, allowing for easy inspection by TSA agents.

Liquids that are exempt from the 3-1-1 rule include medications, baby formula and food, and breast milk. These items are allowed in reasonable quantities that exceed the 3.4-ounce limit and do not need to be placed in a quart-sized bag. However, they should still be declared to the TSA officer for inspection.

It is essential to note that the 3-1-1 rule applies to all liquids, including water, beverages, shampoo, toothpaste, lotions, and other similar products. If you wish to bring any liquid items larger than 3.4 ounces, they must be packed in checked baggage instead of carry-on luggage.

It is crucial to pack your quart-sized bag of liquids in an easily accessible place in your carry-on luggage. When you arrive at the security checkpoint, you will be required to remove the bag from your carry-on and place it in a bin for separate screening. This ensures that the TSA agents can inspect your liquids without any issues.

If you fail to follow the 3-1-1 rule, TSA may require you to dispose of the liquid items or transfer them to your checked baggage. It is always recommended to double-check the regulations regarding liquids before your flight to avoid any inconvenience at the security checkpoint.

In conclusion, when flying to the United States, passengers are allowed to bring a quart-sized bag of liquids in containers that are 3.4 ounces or less per item. Liquids that exceed this limit should be packed in checked baggage. Exemptions to the 3-1-1 rule include medications, baby formula and food, and breast milk. Remember to pack your liquids in an easily accessible place and be prepared to remove the quart-sized bag for separate screening at the security checkpoint. By being aware of these regulations and following the guidelines, you can ensure a smooth and hassle-free travel experience.

Navigating New Mexico Travel Restrictions: What You Need to Know

When traveling to the US, there are certain restrictions on carrying liquids in your hand luggage. The Transportation Security Administration (TSA) has implemented these restrictions in order to ensure the safety and security of passengers. However, there are a few exceptions to these liquid restrictions that travelers should be aware of.

The general rule is that you are allowed to carry liquids in containers that are 3.4 ounces (100 milliliters) or less per item, and all items must fit in a clear, quart-sized bag. This includes items such as toiletries, medicines, and beverages. These restrictions apply to both domestic and international flights.

However, there are a few exceptions to these restrictions. The following items are allowed in larger quantities:

• Prescription medications: If you have prescription medications, you are allowed to carry them in larger quantities than the standard liquid restrictions. It is recommended to carry a copy of your prescription or a letter from your doctor to avoid any issues during security checks.
• Baby formula and breast milk: If you are traveling with a baby or toddler, you are allowed to carry baby formula and breast milk in larger quantities. These items do not need to be in a clear, quart-sized bag. It is advisable to inform the security officers about these items during the screening process.
• Liquids purchased at the airport: If you have purchased liquids, such as beverages or perfume, at the duty-free shops located after the security checkpoint, you are allowed to carry these items in larger quantities. These liquids should be placed in a secure, tamper-evident bag, which will be provided by the shop. You will need to show proof of purchase when going through security.
• Medically necessary liquids: If you have medically necessary liquids, such as insulin or liquid nutrition, you are allowed to carry them in larger quantities. It is recommended to have a letter from your doctor explaining the need for these items.

It is important to note that even if you are allowed to carry these liquids in larger quantities, they may still undergo additional screening by the security officers. It is always a good idea to arrive at the airport early to allow enough time for the screening process.

In conclusion, while there are restrictions on carrying liquids when traveling to the US, there are some exceptions to these restrictions. If you have prescription medications, baby formula, liquids purchased at the airport, or medically necessary liquids, you may be allowed to carry them in larger quantities. However, it is important to follow the guidelines and inform the security officers about these items during the screening process.

Understanding the Temporary Green Card Travel Restrictions: What You Need to Know

When traveling to the US, there are certain rules and regulations regarding the items that can be packed in checked luggage, especially when it comes to liquid items. This article aims to provide information about whether or not liquid items can be packed in checked luggage when traveling to the US.

The Transportation Security Administration (TSA) has specific guidelines when it comes to carrying liquids in your checked luggage. In general, liquids are allowed in checked luggage; however, there are certain restrictions and precautions that need to be followed.

According to the TSA's rules, all liquid items in checked luggage must be in containers that have a capacity of 3.4 ounces (100 milliliters) or less. These containers must be placed in a clear, plastic, quart-sized bag. Each passenger is allowed one quart-sized bag of liquids in their checked luggage.

Examples of liquid items that can be packed in checked luggage include shampoo, conditioner, mouthwash, perfume, and other similar personal care products. It is important to note that these liquids must be in containers that meet the size requirements and placed in the plastic bag for easy inspection.

However, there are certain exceptions to the liquid restrictions. Prescription medications and over-the-counter medications are allowed in larger quantities. It is recommended to carry a prescription or doctor's note for any liquid medication that exceeds the 3.4-ounce limit.

Additionally, baby formula, breast milk, and juice for infants or toddlers are allowed in larger quantities. These items may be subject to additional screening at the security checkpoint.

It is important to follow these guidelines to ensure a smooth and hassle-free travel experience. If any liquid items in checked luggage do not meet the size requirements or are not properly placed in the plastic bag, they may be confiscated or discarded by airport security.

In conclusion, liquid items can be packed in checked luggage when traveling to the US, but there are specific rules and restrictions that need to be followed. Liquids must be in containers of 3.4 ounces or less and placed in a clear, plastic, quart-sized bag. It is essential to comply with these guidelines to avoid any issues during the security screening process.

Understanding the TN Visa Travel Restrictions: What You Need to Know

When traveling to the United States, it is crucial to be aware of the specific guidelines regarding carrying medications and medical liquids. Whether you are visiting the U.S. for leisure or medical treatment, it is essential to understand the rules to avoid any inconvenience or potential problems at the airport.

The Transportation Security Administration (TSA) has specific guidelines regarding medications and medical liquids that passengers can bring on board. These guidelines ensure the safety and security of passengers while maintaining the necessary precautions for potentially harmful substances.

First and foremost, it is recommended to pack all medications in your carry-on luggage. This is because checked baggage can sometimes get lost or delayed, leaving you without access to your essential medications. By keeping them in your carry-on, you will have them readily available during your journey.

To comply with TSA regulations, it is crucial to keep medications properly labeled. Original prescription bottles or vials with your name, the medication name, and the prescribing doctor's information should be included. If you are carrying over-the-counter medication, it is still wise to have it in its original packaging.

In addition to prescription medications, you can also bring over-the-counter medications such as pain relievers, antacids, and allergy medications. However, these should be in amounts reasonable for personal use during your trip. It is advisable to bring only the necessary quantity of medication needed for the duration of your stay in the United States.

When it comes to medical liquids, TSA allows travelers to bring them in containers larger than the standard 3.4 ounces (100 milliliters). However, these liquids must be presented for inspection and may require additional screening. Travelers are advised to notify TSA officers about their medical liquids when they reach the security checkpoint to facilitate the screening process.

It is also essential to note that some medication and medical liquids may be subject to additional requirements or restrictions. For example, certain narcotics or controlled substances require additional documentation or approval from relevant authorities. It is recommended to consult with your prescribing physician and check with the U.S. embassy or consulate in your home country to ensure compliance and avoid any issues.

In case you are carrying liquid medications that exceed the standard allowed limit, such as large quantities of liquid prescription soap, contact lens solution, or saline solution, you can request a medical declaration at the security checkpoint. This declaration form explains your medical condition and the need for the specific liquid medication. While this process may cause a slight delay, it allows you to carry your necessary medical liquids.

It is important to emphasize that the TSA's guidelines are subject to change, so it is always prudent to check the latest updates before your trip. The TSA website and mobile app provide detailed information about what is allowed and prohibited in carry-on luggage. Being aware of these guidelines and planning accordingly will ensure a smooth travel experience and help you stay in compliance with the regulations when bringing medications and medical liquids to the United States.

Rules for Liquids in Checked Baggage: The Complete Guide

TripSavvy / Ashley DeLeon 

DIY Ways to Secure Your Packed Liquids

Go with the pros, add padding, anticipate inspections, tips for packing liquids in checked baggage.

You can carry liquids in checked baggage, but you will have to do some research and take precautions. First, you must find out which liquids are not allowed on airplanes regardless of where you pack them. The Transportation Security Administration (TSA) has a list of these prohibited liquids on its website . You should also look at the Federal Aviation Administration's list of hazardous materials. Never try to bring prohibited materials with you when you fly.

After you've done your research, you must determine whether you can bring the liquid items of your choosing to your destination. If you plan to carry several bottles of wine, for instance, you may not be able to bring them into certain U.S. states due to liquor import regulations. Travelers flying to or from Canada will want to read the Canadian air travel regulations, and visitors to the UK should read the United Kingdom's list of items you may carry in hand (carry-on) and hold (checked) baggage.

Your next step is to decide whether you want to pack colored liquids, such as red wine or nail polish, which could damage your clothing. Carrying any colored liquid can be risky. Decision-making factors include whether these items are available at your destination and whether your itinerary is flexible enough to allow you to purchase them locally, rather than bring those liquids with you.

Finally, you will need to carefully pack your liquid items so they will not break or leak. There are several ways to accomplish this. Read on for our complete guide on what to know before packing liquids for your next trip.

To prevent leaks, wrap the top of your bottle or container with duct tape so the cap stays on. (You may also want to pack a small pair of sharp scissors in your checked bag so you will be able to remove the tape later.) Put the container into a zipper-top plastic bag and seal the bag closed. Next, place that bag into a larger zipper-top bag and seal it closed, pressing out all the air as you do so. Wrap the whole thing in bubble wrap if the container is breakable. Finally, wrap that bundle in a towel or in clothing. (Many travelers suggest using dirty laundry for this.) Place the wrapped bottle or container in the middle of your largest suitcase, surrounded by clothing and other soft items.

A variation on this method involves using a hard-sided plastic or cardboard container to protect your liquid item. Use a small cardboard box or a sealed plastic container. Double-bag the liquid item as described above. Then, place it in the container and pad it with crushed newspapers, plastic air pillows or crumpled plastic grocery bags. Tape the box shut and pack it in the center of your suitcase.

You can buy styrofoam or bubble wrap "shippers," which are sealable padded bags. Brand names include the inflatable VinniBag or the Wine Mummy. Boxes made especially for transporting glass and liquid items are another option. Your local wine shop or pack-and-wrap store may carry shippers. Be aware that the bubble wrap bags will keep escaping liquid from staining your clothes, but may not prevent glass bottles from breaking. The box shipper will take up more room in your luggage. While it may not prevent liquid from escaping, the box shipper minimizes the risk of breakage.

Protect your liquid items by placing them in the middle of your suitcase, completely surrounded by clothing and other items. Be aware that your suitcase could be dropped or crushed, perhaps more than once, on its way to your destination. It may even be dragged on the ground behind a luggage cart. If you can choose from several suitcases, pick the one with the stiffest sides and pack it as tightly as you can to better cushion your liquid items.

If you pack liquid items in your checked bag, assume that your bag will be inspected by a baggage security screener. The screening officer will see your liquid item on the baggage scanner and will probably need to take a closer look at it. Do not pack valuables, even liquid ones, or prescription drugs in your checked baggage.

• Careful packing and padding will increase your chances of success, so make sure to transfer all liquids to leak-proof containers.
• Pare down your packing. Not everything can fit in your suitcase! Decide what toiletries you may find up for grabs in your hotel room, and edit, edit, edit.
• Two-in-one items are always a good idea.
• If you have a large-sized soap or shampoo that you really want to take on your trip, invest in travel-sized toiletry bottles . This way, you can pour some into the correctly sized bottle and still be allowed to take it with you on your trip.

For travelers, it can often be confusing which items to pack in your carry-on luggage. For example, are you allowed to bring that jar of jam you just purchased on your travels? Not likely. Unfortunately, unless that jam is less than 3.4 ounces, you’ll have to put it in your checked luggage. What about your sports equipment to stay active on your vacation? It depends. Tennis rackets are allowed, but ski poles are a no-go.

There are also some items, like lighters and batteries, which are allowed in carry-on luggage OR checked luggage, but not both. Other items are not allowed on the plane at all, such as cooking spray and fireworks.

Confused by the carry-on luggage rules and regulations? Well, you’re not alone. To make it easier, w e’ve made sense of the TSA’s extensive list and compiled a list of all the items you shouldn’t be packing in your carry-on luggage. 

TSA has rules in place to make sure that your flight is safe and secure. For liquids, aerosols, gels, creams, and pastes in your carry-on luggage, you’ll need to adhere to the 3-1-1 rule . This means that each item must be less than 3.4 ounces (100 milliliters) and all items must fit in a 1-quart-sized bag. You are also not allowed to bring on items that are otherwise deemed hazardous.

Hot Tip: Want even more details? Check out how to easily get through TSA airport security for some other great tips. We also have tons of answers to your TSA airport security frequently asked questions .

As we noted above, some items are allowed in your checked luggage, but not your carry-on, or not allowed in either your carry-on or checked luggage.

We’ll specifically call out those items in the list below, so you’ll know how to pack for your flight.

Carry-On Luggage Restrictions

Our list includes things that are strictly prohibited due to TSA rules and regulations , but keep in mind that there are other items that you’ll want to consider avoiding in order to be a good traveler. These include smellier items (think tuna fish sandwiches) and things that could cause an allergic reaction in other passengers, such as peanut butter or peanut-based products.

Also remember the 3-1-1 rule for liquids, creams, etc. — this means that many travel-sized versions of these items are perfectly acceptable to bring!

Lastly, if you are traveling with powders larger than 12 ounces (350 milliliters), the TSA encourages you to pack them in your checked luggage. This isn’t a requirement but could save you a bit of hassle going through security.

Hot Tip: Items purchased past security are not impacted by this list and can be brought on board in any quantity. However, if you have a layover and have to go through security again, you will be subjected to the list below.

All of the items below should not be included in your carry-on luggage , though additional clarifications as marked as follows:

*Less than 3.4 ounces (100 milliliters) allowed 

 ⁺Not allowed in carry-on nor checked luggage

^Special instructions/Check with the airline

You’ll notice that certain things don’t appear on this list. That is because they are allowed. For example, b reast milk , formula, and baby food are permitted on board and do not need to comply with the 3-1-1 restrictions.

In addition, items like frozen meat, seafood, ice cream, and other food are allowed, however, if the food is packed with ice or ice packs in a cooler or another container, the ice or ice packs must be completely frozen when brought through screening.

All the remaining items should be placed in your checked luggage (unless you can comply with the 3-1-1 rules or the item is frozen solid).

• Alcoholic beverages * (check with your airline regarding the allowable amount; must be in unopened retail packaging)
• Alcoholic beverages over 140 proof ⁺

Bottom Line: If you’re considering packing something and it’s not on this list, check out the TSA’s website to check if it’s allowed or you can even tweet the TSA @AskTSA .

When traveling internationally, most countries (and even a few domestic destinations such as Hawaii , Puerto Rico, and the U.S. Virgin Islands ) prohibit you from bringing in meats, fruit, vegetables, plants, and other agricultural products . While the TSA will allow you to bring a fresh snack, such as an apple or carrot sticks, through security and onto your flight, make sure you eat it on the plane. Otherwise, you could run into issues upon arrival.

Duty-free alcohol, perfume, and other liquids  that you buy from the airport are allowed on your airplane in your carry-on luggage. However, remember to leave the receipt inside the security bag. In addition, if you have a connecting flight at another airport, you may have to end up putting it in your checked luggage for the next leg of your journey.

Other destinations may have rules regarding the types of items that you are allowed to bring into the country as well, including currency, medication, weapons, etc. This is always good to research before leaving for your trip.

Using this list can help you be realistic about what you need to take on your vacation and also let you know which items you might need to purchase once you arrive.

Knowing what items to pack and what items to avoid packing in your carry-on luggage can help make your trip through TSA security quick and painless. Following this list is especially important if you’re only traveling with your carry-on luggage!

Frequently Asked Questions

What items are allowed and not allowed on an airplane.

There are many allowable items in your carry-on luggage! You must adhere to the 3-1-1 rule for liquids, creams, and gels, and not bring things that can potentially be hazardous. Check out the list above for carry-on luggage guidelines.

Can you take sunscreen on a plane?

Yes, sunscreen is allowed in your carry-on luggage, but must be in a 3.4-ounce-sized (or less) container. You’re allowed to take as many travel-sized liquids as can fit into 1 quart-sized bag.

Is toothpaste considered a liquid by the TSA?

Yes, toothpaste must adhere to the 3-1-1 rule for liquids and gels. Toothpaste can be brought through TSA security in your carry-on as long as it is 3.4 ounces (100 milliliters) or less and placed in a 1-quart bag. If your toothpaste is bigger, put it in your checked luggage or purchase some upon arrival.

Can you bring metal in your carry-on?

Yes, metal is allowed in your carry-on luggage. In fact, when you are going through the metal detector at TSA security, you are often asked to remove metal items (such as your belt, shoes with metal, etc.) in order to avoid setting off the metal detector. This will pass through the x-ray machine for further inspection, but is allowed to be brought on the plane with you.

Can I bring a razor in my carry-on?

Electric and disposable razors (and replacement cartridges) are both permitted in your carry-on luggage. This is what the majority of people use, per the TSA .

Single razor blades or razors with removable blades must be packed in your checked luggage.

The U.K. Ended Its Travel-Size Liquid Rule for Carry-Ons—Will the U.S. Do the Same?

By Jessica Puckett

Passing through airport security in the U.K. is about to get easier and more streamlined, as U.K. officials announced that the rule mandating liquids in carry-on bags be 100ml (3.4 ounces) or less will no longer be enforced, starting in June 2024. 

When the rule ends, passengers will be able to carry-on liquids measuring up to two liters in volume, the BBC reports . Additionally, passengers will no longer need to remove electronics from bags, such as laptops. Previously, major airports in the U.K., such as London Heathrow, were known for their stringent enforcements of the liquid rules.

In the U.S., similar policies are still in effect at airports around the country, with the TSA enforcing its so-called “ 3-1-1 ” liquid rule for carry-on bags: all liquids must be 3.4 ounces or less and fit in a single, one-quart clear bag. (Though there are  some exceptions to those rules.)

The more relaxed screening policies in the U.K. are possible thanks to new X-ray scanners that use computed tomography (CT) technology to produce more detailed, 3D images of luggage contents. (The technology is similar to a CT scan you might get at a hospital.) Most airports in the U.K. will need to upgrade their X-ray machines to the newer high-tech versions by June 2024. 

The same enhanced CT technology has been in use at U.S. airports for several years now, with the TSA rapidly expanding the scanners to dozens of airports nationwide. As of May 2022, the agency said it had deployed at least 402 CT units to 163 airports around the country. Over the summer, officials installed more of the scanners at additional airport checkpoints in anticipation of an uptick in air travelers, including at Billings Logan International Airport in Montana , Albany International Airport in New York, Buffalo Niagara International Airport in New York, Cincinnati/Northern Kentucky International Airport and Raleigh-Durham International Airport in North Carolina, the TSA  said in a release . 

With that in mind, will the TSA follow the U.K.’s lead and ditch its rules for carry-on liquids? Currently at U.S. security checkpoints with CT scanners, passengers already have somewhat more relaxed screening rules, as they aren’t required to remove their travel-size liquids, electronics, or food from their carry-on bags, according to the TSA. That was a precursor step to the new U.K. policy at  London City airport , which received CT scanners in November 2022 and announced that passengers no longer had to remove any items from their bags. 

But some industry analysts say scanning equipment is only one piece of the puzzle . “I believe that TSA and other aviation security organizations will study the results from the UK’s decision closely and carefully,” says Henry Harteveldt, an aviation expert and president of Atmosphere Research. “If behavioral profiling and other similar tools allow security organizations to potentially detect people who may pose a danger to airline crews and passengers, it may help reduce the need for measures such as the 100ml limit on liquids and the TSA’s 3-1-1 policy.”

Indeed, it seems U.S. officials plan to take it slow when considering any changes to the current TSA 3.4-oz liquid rule, which has been the international standard since it was implemented in 2006. “Computed Tomography technology produces 3-D images that can be rotated and combined with advanced detection algorithms to produce a substantial improvement in security screening,” Robert Carter Langston, TSA's press secretary, said in an emailed statement. “While we have them deployed at more checkpoints, we are years away from announcing a change to the current liquids rule.” 

Although U.S. passengers still need to pack travel-size liquids for the time being, that doesn’t mean that the security checkpoint hasn’t been seeing other improvements. Aside from rolling out more CT scanners, TSA has been deploying credential authentication technology: new ID scanners that don’t require passengers to show their boarding passes . Earlier in 2022, the agency also began accepting digital IDs from the Apple Wallet app at certain airports and testing an expansion of facial recognition to whisk travelers through even faster.

Airlines will now be required to give automatic cash refunds for canceled and delayed flights

The Biden administration issued final rules Wednesday to require airlines to automatically issue cash refunds for things like delayed flights and to better disclose fees for baggage or canceling a reservation.

The Transportation Department said airlines will be required to provide automatic cash refunds within a few days for canceled flights and “significant” delays.

Under current regulations, airlines decide how long a delay must last before triggering refunds. The administration is removing that wiggle room by defining a significant delay as lasting at least three hours for domestic flights and six hours for international ones.

Airlines still will be allowed to offer another flight or a travel credit instead, but consumers can reject the offer.

The rule will also apply to refunds of checked-bag fees if the bag isn’t delivered within 12 hours for domestic flights or 15 to 30 hours for international flights. And it will apply to fees for things such as seat selection or an internet connection if the airline fails to provide the service.

Complaints about refunds skyrocketed during the COVID-19 pandemic, as airlines canceled flights and, even when they didn’t, many people didn’t feel safe sharing a plane cabin with other passengers.

Airlines for America, a trade group for large U.S. carriers, noted that refund complaints to the Transportation Department have fallen sharply since mid-2020. A spokesperson for the group said airlines “offer a range of options — including fully refundable fares — to increase accessibility to air travel and to help customers make ticket selections that best fit their needs.”

The group said the 11 largest U.S. airlines issued $43 billion in customer refunds from 2020 through 2023.

The Transportation Department issued a separate rule requiring airlines and ticket agents to disclose upfront what they charge for checked and carry-on bags and canceling or changing a reservation. On airline websites, the fees must be shown the first time customers see a price and schedule.

The rule will also oblige airlines to tell passengers they have a guaranteed seat they are not required to pay extra for, although it does not bar airlines from charging people to choose specific seats. Many airlines now charge extra for certain spots, including exit-row seats and those near the front of the cabin.

The agency said the rule will save consumers more than $500 million a year.

Airlines for America said its members “offer transparency and vast choice to consumers” from their first search.

The new rules will take effect over the next two years. They are part of a broad administration attack on what President Joe Biden calls “junk fees.” Last week, Transportation Secretary Pete Buttigieg announced that his department will let state officials in 15 states help enforce federal airline consumer protection laws .

Trans care restrictions force some families to travel hours, spend hundreds for treatment

More than 20 states have gender-affirming care restrictions.

Misty Stamm was working tirelessly to figure out the details: waking up early, the hourslong drives, booking hotels and finding doctors who could legally administer gender-affirming hormone therapy to her 16-year-old transgender daughter.

Stamm is living in one of the 24 states where legislation is restricting gender-affirming health care for transgender youth, so she and parents like her must make long, expensive trips out of their home states to find the care their children need, according to a new report from the Campaign for Southern Equality Research and Policy Center.

“If we didn't have the care, I don't think she'd be alive,” said Stamm.

Stamm, who lives in Tennessee, drove five hours to get her daughter to a gender clinic in Ohio when her family first started considering care options. She wanted her daughter to be seen by a physician in person.

With new gender-affirming care restrictions set to go into effect soon in Ohio, Stamm and her daughter have since turned to a telehealth provider in Virginia.

However, they still have to drive two hours to Virginia for the online appointment, as to not break Tennessee law, which also bans telehealth providers from providing care and treatments like puberty blockers and hormone therapies to a minor located in the state.

Stamm told ABC News that the time, effort and money they’re spending to access care is worth it.

When she came out as transgender at 13, “the mental health issues stopped completely,” said Stamm. “That affirmed to us that this was the right thing.”

Stamm's daughter had been in counseling and therapy since she was in fifth grade, struggling with her mental health and experiencing depression, anxiety and suicidal ideations.

At age 14, Stamm's daughter received puberty blockers to temporarily pause the development of physical sex characteristics. As her daughter grew older, the family and physicians together decided to move forward with hormone therapy. Throughout this process, they said, psychologists and therapists were consulted and were required for approvals.

“There's no talk of surgery or anything like that,” said Stamm. “That's a decision that she can make when she is an adult.”

Meanwhile, her mental health has progressed exponentially – Stamm said her daughter has since been released by her therapist and is only seen occasionally, as needed.

"She's just doing so well, and if we didn't have access -- we have to have it. She has to have it."

Gas, airfare, lodging and other expenses to cross state lines and access gender-affirming care could cost hundreds to thousands of dollars, the Southern Equality report states.

Stamm says she and her husband have spent likely thousands of dollars in travel costs to get care and are anxiously awaiting the day their daughter turns 18 so she can access care more freely.

The report from Southern Equality Research and Policy Center found that it could take almost 20 hours of driving roundtrip for some families across the South and Midwest to reach a state where trans youth care is legally accessible.

Families with transgender children across southern Florida, Louisiana, Missouri and Texas are the hardest hit, according to the report -- they would need to take a more than eight-hour car ride one way to get to a clinic that serves trans youth.

For Jennifer, an Austin, Texas, resident who asked to go by a pseudonym for safety concerns, said the health care bans in her state threw her family into logistical and financial chaos.

Her 15-year-old daughter’s appointments to begin hormone therapy were canceled before the law in Texas even went into effect. When they sought out care in Louisiana, providers also were canceling appointments.

She sought out the help of local advocacy groups to help her family find a provider in Texas' neighbor to the west, New Mexico.

However, the costs continue to mount: “We are in a position that we could afford to buy plane tickets and stay in a hotel for a couple of nights and pay all of the out-of-pocket expenses for the medical care,” said Jennifer. “For a lot of people, that's probably not an option.”

Though telehealth has expanded opportunities for access to care, policies like those in Tennessee restrict these appointments for prescriptions from happening in the state and force some families like the Stamms to cross borders for online appointments.

Tennessee Gov. Bill Lee, who signed the gender-affirming care ban , has defended the bill against legal challenges.

"Tennessee is committed to protecting children from permanent, life-altering decisions," said Lee in a post on social platform X after the Justice Department argued the law violates the Fourteenth Amendment's Equal Protection Clause.

Supporters of gender-affirming medical care bans argue that children should wait until they’re older to make these medical decisions, and that there needs to be more research on the impact of these procedures on patients.

In the state’s court filings in opposition to a lawsuit against the ban, the state invokes Dobbs v. Jackson Women’s Health Organization – the decision which overturned Roe v. Wade and ended federal protections for abortion rights.

The state argues that Dobbs allows states “to regulate medical treatments” and that it does not discriminate against transgender people because “not all transgender individuals use puberty blockers, hormones, or surgery.”

“This Court should acknowledge divergent views and hold that the responsibility to choose between them rests with the people acting through their elected representatives,” read the state’s filing.

The Tennessee Legislature is now considering a bill that could make it a felony to help a minor access gender-affirming care out-of-state without parental consent.

Transgender care for people under 18 has been a source of contention for state politicians in recent years, impacting a group estimated to make up less than 1.5% of the population ages 13-17, according to an estimate from researchers at the University of California, Los Angeles .

Often due to discrimination, stigma, and gender-related stress, trans youth are at increased risk for poor mental health and suicide, substance use, experiencing violence, and other health risks, according to the Centers for Disease Control and Prevention.

Major national medical associations, including the American Academy of Pediatrics, the American Medical Association, the American Academy of Child and Adolescent Psychiatry, and more than 20 others have argued that gender-affirming care is safe, effective and medically necessary.

“Allowing them to live in their identity is what saves their mental health,” Jennifer said in response to criticism over transgender medical care.

As families continue to seek out avenues for care, Jennifer and Stamm want lawmakers to know that they're just a "normal, regular family."

“I want them to see us as people,” Jennifer said. “We are their neighbors, we are people who teach their kids in school. We are people they work with.”

Stamm adds, "She's just a regular kid, just trying to be a regular kid. … This has just presented so many challenges for her and we feel isolated. Our circle is tight and small ... Hopefully, people will be a little bit more empathetic to what we're going through. And how ridiculous all of this is."

Travel restrictions near Memorial Mall area to continue through summer

As part of the University Hall project , some travel restrictions near the Memorial Mall area will remain in place through the summer.

Some parking spaces along Oval Drive near University Hall have been removed. While Oval Drive is still open, motorists should be aware of construction fencing in front of University Hall. Fencing is also up along the northside of University Hall, closing off the walkway between Schleman Hall. The walkway between University and Stone Halls will remain open throughout the project.

Additionally, fencing is expected to be installed around Heavilon Hall in late June with the goal of demolition for the building starting in early September after preparatory work. As a result of the fencing going up, the walkways near the Brown Laboratory of Chemistry and Grissom Hall will be closed. Pedestrians will be able to walk between Heavilon Hall and the Wetherill Laboratory of Chemistry.

Motorists, pedestrians and bicyclists should use caution in the area and obey all posted signs.

Questions about the project may be directed to Cy Rangel, project executive, at [email protected] . Parking questions may be directed to Parking Facilities at 765-494-9497 or  [email protected]  between 7:30 a.m. and 4:30 p.m. Monday through Friday. The lobby closes at 4 p.m.
